Title: Improvements in telegraph apparatus
Inventor: MASON FREDERICK PERCIVAL
IPC: H04L25/45
Filed: 1966-05-03
Abstract: 1,081,966. Telegraphy. CREED & Co. Ltd. May 3, 1966, No. 19418/66. Heading H4P. A buffering arrangement in a telegraph system in which the rate of the received characters may vary comprises a time base TB1, started by each received Start bit, which feeds the serial data to a first store S1. The fifth stage of the time base energizes a second time base TB2 which generates a signal of duration greater than the minimum interval between successive Start bits but less than the nominal interval between such bits. This signal, while it lasts, prevents TB2 from responding to any further pulse from TB1, and also, after differentiation, resets a second store S2 and then reads the data in S1 to S2. Store S2 is read out by clock pulses from TB3, which has a repetition rate greater than or equal to the nominal character rate. As a result, a character is stored in S1 until S2 is reset, the preceding character having been read from S2 prior to the resetting to a third store S3, from which it is passed to a printer or perforator.

Abstract: 247,087. British Thomson-Houston Co., Ltd., (General Electric Co.). July 31, 1925. ' Controllng extent of travel.-In controlling a motor to follow angular movements of a distant instrument, for example a telescope 11, the original movement takes effect on an inductive device 13 at the transmission end of the control circuit so as to generate an electromotive force depending on the amount and direction of the angle of movement. The energy received is amplified at the receiving end by a pair of 61ectron discharge tubes 24, 25, one for each half of the wave, and may be further amplified by a second pair of electron tubes 33, 34. In the example shown, the amplified three-phase energy is delivered to the stator windings of an induction motor 22 which angularly displaces an inductive winding 18 until its position corresponds to that of the inductive winding 13. The motor 22 may be used to train a search-light 10. In a modification the amplified waves at the receiving end are delivered to a direct current motor having two armatures connected to inductance coils and condensers, or a single armature with differential field windings. In another modification the waves are delivered to differential field windings of a generator which supplies the working motor.

Filed: 1926-08-12
Abstract: 256,986. British Thomson-Houston Co., Ltd., (Assignees of Prince, D. C.). Aug. 12, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Vapour apparatus, arrangements of. - In means for converting alternating current to direct current or vice versa in which regulation of the output voltage is effected by an interphase transformer connected between the supply and load circuits and provided with a saturating winding excited in accordance with the load current, means are provided for modifying the influence of the load current on the excitation of the saturating winding. Fig. 1 shows the regulating arrangement applied to a system in which a direct current load circuit 2 is supplied from a three phase alternating current circuit 1 through transformers 3, 4, 5 and mercury vapour rectifiers 6. 7. The interphase transformer comprises. star-connected pairs of windings 23 - - 28 arranged on coils 29, 30, 31 and connected to the mid points of the main transformer secondaries and through a resistance 11 to the direct current circuit 2. The means forsaturating the cores for effecting regulation comprise windings 32, 33, 34 connected across the resistance 11 in the load circuit and in series with a source of current 36 and a variable resistance 35. The source 36 is of variable voltage opposed to that due to the current in the resistance 11 and affords means in conjunction with the resistance 35 of causing saturation of the cores 29, 30, 31 to take place at different load valves. In alternative arrangements of interphase transformers the windings 23 - - 28 are arranged on three legs of a common core and the saturating winding is arranged on a fourth leg which may be provided with an air gap and with an additional saturating winding connected across the terminals of the circuit 2 whereby the compounding characteristic is modified. In another arrangement, a battery is connected through a valve in opposition to the voltage drop in tha resistance 11 so that 'the load current becomes effective for exciting the saturating windings only when it exceeds a predetermined valve. According to a further alternative, Fig. 5, the saturating winding 38 is connected across a ballast resistance 43 whereby the effect of the load current on the excitation of the saturating winding is reduced at light load. Arrangements are also described in which the regulating devices arc applied to conversion systems in which the main transformer arrangements comprise respectively a single 'transformer having a six phase secondary, and a pair of transformers having three phase secondaries. Alternative arrangements of interphase transformers are also described in which the interphase windings are arranged in oppositely wound pairs so that theeffect of the direct current component is cancelled.

Title: Processes for the production of thixotropic preparations containing copper oxychloride and the products obtained thereby
IPC: A01N59/20
Filed: 1935-07-12
Abstract: Copper oxychloride preparations for use as fungicides are obtained in a thixotropic condition, so that while normally solid or semi solid they may be converted to the liquid condition by mechanical vibration, by kneading together, in a Werner-Pfleiderer or similar machine, copper oyxchloride containing from 20 to 58 per cent of water and a protective colloid in such proportions that the mixture contains at least 600 gms. of copper oxychloride per litre.  Suitable protective colloids are sulphite cellulose liquor, molasses and dextrin.  A washed precipitate of copper oxychloride is partly freed from water by pressure, centrifuging or evaporation and then is kneaded with sulphite lye or other protective colloid with or without the addition of a little calcium carbonate to eliminate traces of soluble copper.  Part of the colloid may be added to the oxychloride precipitate before treatment to remove excess water.  The precipitate is preferably freshly prepared, but dry oxychloride may be used in conjunction with the required quantity of water.  The preparations are diluted with water when used.  Reference is made to known preparations in which (1) a powder of copper oxychloride and a protective colloid is prepared, (2) a cream is made from a concentrated solution of copper chloride and calcium hydrate, and (3) a fresh copper oxychloride precipitate is stirred with a considerable quantity p  of protective colloid and water to form a stiff paste.

Abstract: 182,009. Misener, S. J. July 26, 1921. Leaf filters. - The invention relates to means for reciprocating axially an oscillating pipe provided w i t h nozzles through which wash - water is discharged against the surfaces of filtering- leaves to remove the cakes formed thereon. Rotational oscillations are given to the pipe B either manually or mechanically. A threaded sleeve 21 is loosely mounted on the pipe and is engaged by a fixed nut 22. A pawl 25 on an arm 26 fixed to the pipe engages a pawlwheel 24 fixed on the sleeve 21. The oscillation of the pipe thus causes the sleeve to. move axially through the nut 22. If the movement is to the right in Fig. 3, the end of the sleeve contacts with a collar 20, fixed on the pipe B and pushes the pipe to the right. The pawl 25, Fig. 4, has teeth 28, 29 at either end, the tooth 28 being shown held in engagement with the pawl-wheel 24 by a spring 30. The motion of the sleeve is reversed, when a pin 31 on the pawl contacts with an adjustable stop 33 and the pawl 25 is thrown over to bring the tooth 29 into engagement with the wheel 24. During the movement to. the left the sleeve pushes the pipe by engagement with a collar 27. Motion in this direction is limited by a second adjustable stop 34 which again throws over. the pawl. It is arranged that each spray nozzle shall travel from opposite the centre of one leaf to opposite the centre of the adjacent leaf.
